Enumerate

Explore how the enumerate function in Python transforms iterables by creating tuples of index and value pairs. This lesson helps you understand its use in functional programming for safer and clearer data stream transformations without traditional loops.

Functional programming prefers iterables over lists because there is less risk of side effects. We often need to transform an iterable stream in some way, and Python provides a number of standard functions to do that.
